ATTACHMENT FOR GAS-STOVES.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed January 24, 1908. Serial No. 412,452.

T 0 all whom it may concern:

Be it known that 1, CHARLES M. CLEAV- LAND, a citizen of the UnitedStates, residing at lVausau, in the county of Marathon and State ofWisconsin, have invented a new and useful Attachment for Gas-Stoves, ofwhich the following is a specification.

This invention relates to attachments for gas or other hydrocarbonstoves utilizing burners and its object is to provide means whereby thefuel may be economized by concentrating the heat produced by thecombustion of the fuel.

Another object is to provide an attachment of this character which canbe readily placed in position upon a stove and which permits practicallyall of the generated heat to be utilized for cooking or'other purposes.

lVith these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a section through the attachment, the samebeing shown in position upon a stove a portion of which is shown. Fi 2is a plan view of the attachment, a part of the cover being broken awayto show the interior construction of the receptacle portion of theattachment.

Referring to the figures by characters of reference, 1 designates aportion of a stove burner 2 of any suitable form disposed therebelow,this burner being preferably of the ordinary round form. The stove tophas the usual opening 3 over which the utensils to be heated areordinarily placed and this opening is designed to receive the main ordeflecting member of the attachment. This member consists of an invertedfrusto-conical body 4 having a cylindrical extension 5 at its lower orsmall end designed to surround the burner 2, the same being spacedtherefrom for a suflicient distance to permit enough air to pass theburner to support combustionf An annular flange 6 is disposed at theupper or large 'end of the body 4 and is designed to rest upon the stovebody having a body. This flange is provided with an upstandingperipheral ring 7 constltuting a retainer.

A cylindrical supporting body 8 is designed to rest upon the flange 6and to be being necessary to surrounded by ring 7, this body being openat its upper end and having a handle 9 whereby it can be convenientlymanipulated. A lining 10 of asbestos or other suitable insulatingmaterial is preferably located within the body 8.

A receptacle is used in connection with the attachment and consists of abody 11 tapered toward its lower or closed end and having its wallfluted or corrugated as shown at 12, said wall being provided at itsupper end with an annular flange 13 extending across the channels formedby the corrugations and being so proportioned as to rest upon the upperedge of body 8 so as to support the body 11. An annular retaining rib 14is formed at the periphery of flange 13 and constitutes means forholding a lid 15 upon the receptacle. This lid may be of any preferredtransverse contour and is designed to rest flat upon flange 13. Openings16 are formed in the flange 13 beyond the outside channels formedbetween corrugations 12 and these openings are designed to register withcorresponding openings 17 formed in the lid 15.

It will be apparent scribed attachment can be conveniently used withhydrocarbon stoves of various forms it have the burner located below anopening formed in the stove top. In order to place the attachment inposition the body 4 is suspended within the opening 3 so that thecylindrical extension 5 will surround the burner 2. The body 8 is thenpositioned upon flange 6 after which the receptacle 11 is supportedwithin the body 8 by placing its flange 13 thereon. The food to becooked or the article to be heated is then placed within receptacle 11and the fuel is ignited at burner 2. Combustion will be supported by airentering the extension 5 and all of the products of combustion will passupward through bodies 4 and 8 and can only escape through the openings16 and 17. The lining 10 prevents radiation of heat and the body 4likewise prevents the waste of heat which usually occurs between theburner and the stove top. It will be apparent that the esca e of thecombustion products can be readi y controlled by means of the cover 15.This cover can be so positioned as to entirely or partly close theopenings 16. It will be apparent of course that an attachment such asherein described serves to that the herein degreatly economize the heatand. permits the reduction of the quantity of fuel consumed Withoutreducing the efliciency of the stove. It Will be obvious that theattachment can 5 be made in various shapes and sizes to fit stoves ofdifferent sizes.

If preferred, a bail such as shown at 18 may be connected to the body 8.The body 4 can be provided With an inner lining of in sulating materialsuch as indicated at 19 although this lining may be dispensed With, ifdesired. Although the device has been shown with a kettle used inconnection therewith it is to be understood that other forms of utensilsmay be combined With the members 4, 8 and 15 Without materiallydeparting from the invention. I

Vhat is claimed is:

1. An attachment for hydrocarbon stoves comprising an invertedfrusto-conical burner receiving body having an annular support engagingflange, a supporting body mounted upon and held against lateraldisplacement by the flange, a utensil extending into the supporting bodyand having an apertured annular flange bearing upon the supporting body,and an apertured cover revolubly mounted upon the utensil forcontrolling the passage of gases through the apertures in the 2. Anattachment for hydrocarbon stoves comprising an inverted irusto-conicalburner receiving body having an annular support flange, a supportingbody upon and centere by said. flange, a utensil supported Within saidlast mentioned body and having longitudinal corrugations, there being anapsupporting body, a cover revolubl y engaging flange, a supporting bodyupon and centered by the flange, linings Within the frusto-conical andsupporting bodies, and a 4 utensil suspended Within the supporting bodyand spaced therefrom, said utensil having an annular apertured flangebearing upon the supporting body.

4. An attachment for hydrocarbon stoves 5 comprising an invertedfrusto-conical burner receiving body having an annular support engagingflange, a supporting body upon and centered by the flange, liningsWithin the frusto-conical and supporting bodies, a uten 5 sil suspendedWithin the supporting body and spaced therefrom, said utensil having anannular apertured flange bearin upon the mounted upon the utensil andhaving an apertured 6 peripheral portion cooperating With the aperturedflange to regulate the escape of gases from the holding body, theutensils being provided with longitudinal corrugations, each aperture inthe flange being dis 6 posed at the upper end of one of the exteriorpanels formed by the corrugations.

In testimony that I claim the foregoing as my oWn, I have hereto afliXedmy signature in the presence of tWo Witnesses.
